LABORATORY OF BUILDING TECHNOLOGY AND PLANTS
Learning outcomes of the course unit
Knowledge and understanding:
The aim of the teaching is the consolidation of the fundamental skills for the correct and complete interpretation of the technological, energy and environmental building needs to be applied to an existing building in order to carry out its comprehensive and detailed analysis. The evaluation of the most appropriate and sustainable methods is functional to transformation, adaptation and recovery of the selected building.
The ability to choose and correctly use the technical components, elements and tools for energy, environmental and functional adaptation of the building will be acquired, as well as the ability to identify passive bioclimatic intervention strategies for an existing building.
Autonomy of judgment:
At the end of the course, the student must have developed the ability to critically evaluate which tools and techniques of retrofit and restoration of the building are the most suitable with regards to regulatory needs, which ones are the most advantageous choices in terms of performance achieved.
Students will develop the ability to describe, communicate and represent at various scales the choices made for the recovery and energy retrofit of the building, for its envelope component and for building system plant, through the use of the most appropriate methods, tools and calculations.
The lectures, practical exercises and site visits aim to consolidate the student's skills in the correct approach existing context and existing building: the student should have matured the knowledge and skills of the discipline to face, in the future, an in-depth study and autonomous application of these aspects.
Knowledge of the most common technologies for the building envelope, main concepts of building statics, basic notions of building thermophysics.
Course contents summary
Starting from the project of an existing building, the laboratory lessons are aimed at providing the student with the skills to adapt an existing building to the energy containment regulations, to prepare technical documents, functional to the redevelopment project (i.e, preparing a final report pursuant to Law 10 / 91). Monographic lessons deepen the individual topics, functional to the laboratory project activity.
The analysis of complex construction elements are also assessed and critically evaluated through the display of exemplary application case studies at the building scale. The project is analyzed and / or modified to meet the regulatory requirements regarding the containment of energy consumption, with attention to the use of both active and passive plant systems, to the presence of environmentally friendly or certified materials (EPD) for the construction of the building envelope, in accordance with the law and to ensure a high standard of living. The calculation procedures allowed for the preparation of an APE are also illustrated, to allow the student to simulate a verification of the global energy behavior of a building, up to the preparation of an energy performance certificate, through the use of C.T.I.
1337 / 5000
The class is divided into lectures (1/3), laboratory activities (1/3), through direct experiences on site or guided tours (1/3). The lerning modules for the theoretical part will be dedicated to the different materials and technologies / building components, to their different performances, and for each section numerous application examples on existing cases will be presented: performance for building components, performance of use and well-being, performance of safety and harmlessness, performance of integrability and appearance, performance of maintenance and management, performance of duration. The building system will be presented and evaluated trough: environmental system and technological system, environmental units and technological units. Main recovery solutions, from traditional to innovative solutions. Evaluation of the overall energy performance of the building, through hints of national energy legislation and the regional laws about energy consumption reduction strategies.
Innovative, new generation materials, nanotechnology and environmental effects (LCA approach and environmental product certifications) will be considered. The main energy standards in use today, from the passive standard to the NZEB standard will be analysed.

The teaching methods are divided into lectures and some seminars with external actors, with specific focus on building technologies, building materials, and case studies’ evaluations. The lessons will include laboratory activities where students will work individually or in teams for the preparation of a retrofit project and if possible, some on site visits. The practical activity of the laboratory involves the projects preparations and the presentation and analysis of real case studies, through surveys, graphic and technical drawings and numerical and three-dimensional data of the case -study.
Assessment methods and criteria
The exam involves the presentation of an energy and environmental redevelopment project for an assigned case study, which will include the critical analysis of the performance needs of the building envelope and the plant component, the precise analysis of the energy / environmental performance of some selected technical component cases.
The exam is completed with an oral discussion about the project, about its technical annexes and the graphical representation tables.
The complete bibliography and the detailed program of the course will be made available in the first days of lessons.
